adding to or deleting from the total count of CPUs is
performed by any of the following:
modifying total directly (cpu::total)
adding or deleting by hw_path (cpu:hw_path)
if the virtual partition is up, total will be adjusted
automatically (unless the CPUs are already assigned
to the partition)
if the virtual partition is down, the number of CPUs
assigned by hardware path must be less than or
equal to the pre-existing total
if this is the case, you should first modify total to
allow the additional CPU.
adding or deleting by CLP
total will be adjusted automatically
adding to or deleting from the total count of CPUs
assigned to a virtual partition is performed by only
modifying total directly (cpu::total)
adding by num (-a cpu::num)
deletion requires decreasing by num (-d cpu::num) or
by hw_path (-d cpu:hw_path)
adding by num (-a cpu::num)
deletion requires decreasing by num (-d cpu::num)
adding by hw_path (-a cpu:hw_path)
deletion requires deleting by hw_path (-d
cpu:hw_path)
this does adjust total if the virtual partition is up
(unless the CPU is already assigned to the partition);
otherwise, if the virtual partition is down, the number
of CPUs assigned by hardware path must be less than
or equal to the current total
partition can be up or down
adding by hw_path (-a cpu:hw_path)
deletion requires deleting by hw_path (-d
cpu:hw_path)
this does not adjust total
this does not adjust min
requires the partition to be down
